Hi everyone, I'm Durante (the guy who made DSfix), and this is my first Nexus news post. I'd like to provide some information on what is possible with Dark Souls modding at the moment, and what might be possible in the future.

Currently, there are two ways to mod Dark Souls. On the one hand there are program modifications such as DSMfix, the 60 FPS mod and my own DSfix, which work by .dll wrapping. On the other hand, since a few versions DSfix supports overriding any of the textures used by the game with custom ones, which is what most mods on this site are based on.

This texture replacement is complete and should allow you to change any texture used in the game, but it is generally not possible to add transparency to textures which did not feature it before. This is due to the way the game separately handles the rendering of opaque and transparent geometry. Also note that most objects in the game have multiple textures, including diffuse color maps, specularity maps and normal maps.

Beyond modifying textures and making direct changes using wrapper dlls, there's also a lot of interest in being able to change models. Unfortunately, unlike textures which are loaded using a known library function, and for which the storage format is rather straightforward, it's not currently known which 3D model format is used by the game.

That's it for now, I'll keep you up to date on any future developments!
